Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a banknote counting machine that distinguishes the denomination of banknotes by attracting the banknotes loaded in a holder onto a suction shaft and turning them over one by one. It is.

[Conventional technology]

Loading, this type of banknote counting machine was developed in Japanese Patent Application Laid-Open No. 1987-
"Paper sheet counting machine" shown in Publication No. 787 and the Utility Model developed in 1982
There is a ``paper sheet confirmation device in a paper sheet counter'' shown in Japanese Patent No. 129558.

The former type of "paper sheet counting machine" distinguishes the denomination of paper sheets (banknotes) loaded in a holder by adsorbing them onto a suction shaft and flipping them one by one. In other words, it corresponds to the first denomination)
If the banknotes are different from each other, it is determined that the banknotes are of different denominations, or if the denomination cannot be distinguished, the suction shaft is used to interrupt the peeling operation. banknotes (referred to as abnormal banknotes) can be confirmed.

On the other hand, the latter "paper sheet confirmation device in a paper sheet counting machine" is similar to the former "paper sheet counting machine",
This device is designed to check for abnormal banknotes by interrupting the turning-up operation using the suction shaft.In particular, this device allows the user to check the last turned-up banknote from the operating side to make it easier to perform the checking operation at the time of interruption. A mirror is provided for confirmation.

[Problem that the invention seeks to solve]

In other words, in the banknote counting machine configured as described above, when an abnormal banknote is detected, the counting is stopped midway and the count is checked. However, since the abnormal banknote is grouped together at the end of the banknotes that have already been counted, the former In the latter banknote counting machine, the operator has to manually turn over and check only the last abnormal banknote from among the banknotes that have already been counted, and therefore the operability is poor. However, in reality, it is not possible to install a large mirror due to the arrangement of the optical system for discrimination or the separator of the batching device when detecting abnormal banknotes. However, it was not possible to significantly improve the ease of confirmation.

This point will be explained in more detail with reference to the time chart shown in FIG.

First, if the discrimination process for a banknote (banknote Sa shown in FIG. 11) is completed by timing t1 and this banknote is determined to be an abnormal banknote, the next banknote (banknote Sa shown in FIG. 11) is processed at timing t1. The peeling operation of Sb) is prevented by a batch device (separator 25 shown in FIG. 11) (see FIG. 12).

On the other hand, a drive signal (CMD) is applied to the counting motor that rotates the suction shaft (numeral 5 in Fig. 11) until the abnormal banknote Sa is together with the already counted banknotes (banknotes Sc and Sd shown in Fig. 11). The rotation is continued (timing t2).

Then, brake signal (BRK) is sent to the counting motor.
is given (timing t3), and timing t
The suction shaft will completely stop around 4.

This control originates from the use of a batch device that is configured to clearly distinguish between uncounted banknotes and counted banknotes when a set number of banknotes are counted. If the banknotes are separated between the counted banknotes and the counted banknotes,
It has been considered that the operator may not be able to tell which banknote is the separated banknote.

Furthermore, although conventional methods have poor operability, if an abnormality occurs in the detection or discrimination of different denominations, it is possible to continue counting by checking the last bill that was turned over. However, only in the case of double adhesion detection, unless it is confirmed that two or more banknotes were glued together with tape, etc., it is difficult to determine whether or not there was really double adhesion. Alternatively, it was not possible to confirm whether or not only a partial stain on one bill was detected, and it was necessary to start counting again from the beginning.

The present invention has been made in view of the above circumstances, and when an abnormal banknote is detected, the operation of turning over the banknote by a suction shaft is interrupted, and at the same time, the rotary tube in which the suction shaft is arranged is suddenly stopped to remove the abnormal banknote. By stopping the uncounted banknotes and the counted banknotes at a separate position by the suction shaft, and checking the denomination of the abnormal banknote when the separation stop is interrupted, the banknote flipping and discrimination operation is performed from the time the separation stop is interrupted. The object of the present invention is to provide a banknote counting machine that can automatically restart the banknote counting machine.

Further, in the second invention, in the first invention,
When confirming an abnormal banknote that is stopped at a position far from both uncounted banknotes and counted banknotes by the suction shaft, the denomination of the banknote can be entered, and the denomination output during the flipping operation of the suction shaft. It is an object of the present invention to provide a banknote counter capable of calculating the total amount of banknotes loaded in a holder based on information and denomination information input at the time of interruption.

[Means for solving problems]

In order to achieve such an object, in the first invention, banknotes loaded in a holder are attracted to suction shafts evenly arranged on a concentric circle of a rotating cylinder, and the denomination is determined while turning over each banknote one by one. A banknote counting machine designed as described above reads the surface pattern of a banknote and compares this surface pattern with pre-stored reference data to determine the denomination of the banknote and output a denomination code. A discrimination control circuit that outputs an error code when detecting banknotes,
Based on the error code output from the discrimination control circuit, a separator is provided to interrupt the bill flipping operation by the suction shaft, and at the same time as the separator interrupts, the rotation of the rotary tube is suddenly stopped and the abnormal bill is sucked out. Confirm the counting motor that is stopped at a position away from both uncounted banknotes and counted banknotes by the shaft, and the abnormal banknote that is stopped at a position away from both uncounted banknotes and counted banknotes by the separator and counting motor. an operation switch capable of inputting an instruction to restart the banknote flipping operation by the suction shaft from the time of the interruption; and a counting control circuit that releases the interrupted state caused by the separator and the counting motor and automatically restarts the bill flipping/discriminating operation from the point of interruption when an instruction is input.

Further, in a second invention, in a banknote counting machine, the banknotes loaded in a holder are attracted to suction shafts evenly arranged on a concentric circle of a rotating cylinder, and the banknotes are turned over one by one to discriminate the denomination. , by reading the surface pattern of the banknote and comparing this surface pattern with pre-stored reference data.
A discrimination control circuit that discriminates the denomination of this banknote and outputs a denomination code, and also outputs an error code when an abnormal banknote is detected, and based on the error code output from this discrimination control circuit, the banknote is A separator that interrupts the turning operation, and a counter that suddenly stops the rotation of the rotary cylinder at the same time as the separator interrupts the turning operation, and stops the abnormal banknote at a position away from both uncounted banknotes and counted banknotes by the suction shaft. After confirming the abnormal banknote that has been stopped at a position away from uncounted banknotes and counted banknotes by the motor, the separator, and the counting motor, input the denomination code of the abnormal banknote and remove the banknote by the suction shaft. an operating switch capable of inputting an instruction to resume the bill flipping operation from the time of interruption; ,
The interrupted state caused by the separator and counting motor is canceled and the bill flipping and discrimination operation from the point of interruption is automatically restarted, and the denomination code output from the discrimination control circuit and inputted by the operation switch are Based on the denomination code and
and a counting control circuit that calculates the total amount of banknotes loaded into the holder.

[Effect]

According to the first invention, when an error code is output when an abnormal banknote is detected, the operation of turning over the banknote by the suction shaft is interrupted, and at the same time, the rotating tube in which the suction shaft is arranged is suddenly stopped. The abnormal banknote is stopped by the suction shaft at a position away from both uncounted banknotes and counted banknotes, and the denomination of the abnormal banknote is confirmed when this separation stop is interrupted, so that the banknote from the time when this separation stop is interrupted The peel-off determination operation is automatically restarted.

Further, according to the second invention, in the first invention, when the denomination of the abnormal banknote that is stopped at a position away from both the uncounted banknotes and the counted banknotes by the suction shaft is input, the above-described separation stop occurs. The banknote flipping/discriminating operation from the point of interruption is automatically restarted, and the denomination code inputted by the operation switch and automatically determined during counting as the bills are flipped one by one by the suction shaft are automatically restarted. The total amount of banknotes loaded in the holder is calculated based on the output denomination code.

Further, a pressure sensor 11 is provided in the middle of the suction pipe 7, and this pressure sensor 11 detects whether the vacuum pressure in the suction pipe 7 has increased to a level that can attract banknotes. It is becoming more and more common.

On the other hand, an exhaust pipe 13 is connected to the exhaust port 12 of the vacuum pump 8, and the tip of the exhaust pipe 13 blows exhaust gas onto the sides of the banknotes S to facilitate separation of the banknotes S from each other. On the other hand, an exhaust nozzle 14 is provided in the middle of the exhaust pipe line 13 to switch the exhaust to a discharge port 15 when banknotes are not being counted to prevent the generation of noise from the exhaust nozzle 14. A solenoid valve 16 is provided.

In addition, each of the suction shafts 5 has a structure shown in FIGS.
As shown in FIG. 3, a pair of position regulating pieces 5a are fixed. This position regulating piece 5a is connected to the suction shaft 5
The opening 10 of the suction shaft 5 protrudes from the side surface of the suction shaft 5.
When the outside air is sucked through the opening 10 and the bill is attracted to the suction shaft 5, it supports the bill from the side and prevents the bill from falling or folding. It is now possible to prevent In this way, the position regulating piece 5a
, the suction shaft 5 maintains the suction-separated banknote in an upright state, and the banknote is placed in the position where it is detected whether or not double feeding is being carried out (the position Sa where the banknote is suction-separated in FIG. 1). positioning is now performed.

Further, a plurality of actuation pieces 17 made of magnetic material are attached to the outer circumference of the rotary cylinder 3, and each suction shaft 5 is moved to a standby position (opening) depending on whether or not these actuation pieces 17 actuate the magnetic sensor 18. 10 is in the starting position (opening 1
0 is in the position just before directly facing the bill, and the inside of the suction shaft 5 is in a position where it is cut off from the vacuum pump 8.

In addition, in FIG. 3, reference numeral 19 is a counting motor that drives the rotary cylinder 3 via a belt 20;
1 is a pump motor that drives the vacuum pump 8 via a belt 22; 23 is a holder motor that rotates the holder 1; 24A and 24B are
Holder 1 in closed position (position close to suction shaft 5)
This is a holder position detection switch that detects whether the holder is in the closed position (a position away from the suction shaft 5).

Further, a separator 25 is provided near the rotary cylinder 3, and this separator 25 is connected to the shaft 26.

1 in the counterclockwise direction in FIG. 1, and is further operated by the batch solenoid 28 to turn it in the clockwise direction in FIG. 1. The separator 25 has a function (to prevent peeling) by being inserted between a banknote that has already been turned over and a banknote that has not yet been turned over when a banknote of a different denomination is detected, as will be described later. function).

Next, a stamping mechanism for stamping a confirmation stamp on a bundle of banknotes will be explained with reference to FIG. 1. 1 is a seal holding member provided in the holder 1, and the seal holding member 30 supports a seal 31 so as to be movable in the direction of the arrow E-L, and the seal holding member 30 supports a seal 31 movably in the direction of the arrow E-L. It is movably supported so as to be close to and away from S. Further, a dial 32 is provided at the base end of the holder 1, and by rotating this dial 32, the seal 31 moves in the direction of the arrow E-L, and the seal 31 is stamped on the seal 31. 31a is aligned with the band seal B.

Further, on the base supporting the holder 1, there is a shaft 33.

1a is brought close to the band seal, thereby making it possible to stamp the band seal.

Next, a mechanism for detecting double feeding of banknotes turned over by the suction shaft 5 will be described with reference to FIG. 1.

In FIG. 1, reference numerals 37 and 38 respectively indicate a double feed detection lamp and a light-receiving element (these elements constitute a double-feed detection sensor), and reference numeral 39 indicates a light-receiving element. This is a condensing lens that condenses light.

The double feed detection lamp 37 and the light receiving element 3
8 are both provided facing the rotary tube 3 side, and the light beam emitted from the double feed detection lamp 37 is irradiated from a direction crossing the turned-over banknote Sa, and The beam is irradiated to approximately the center of the turned-up portion of the banknote Sa.

And the banknotes that were irradiated with light in this way
The amount of light transmitted through the banknote Sa, that is, the amount of transmitted light, is detected by the light receiving element 38, and the double feeding is determined based on the amount of transmitted light detected by the light receiving element 38. . That is, if the amount of transmitted light is greater than a predetermined value, normal feeding (single sheet feeding) is determined, and if the amount of transmitted light is less than a predetermined value, it is determined to be double feeding.

Next, a discrimination mechanism for discriminating the denomination and front and back of banknotes will be explained with reference to FIGS. 1 and 2.

In the figure, the reference numeral 40 indicates a light projector that irradiates light onto the stacked frontmost banknotes Sb.
1 is a light receiver (detection element) that receives the reflected light of the light irradiated onto the banknote Sb from the projector 40, and the light beam emitted from the projector 40 is indicated by a chain double-dashed line on the banknote Sb. The area including area E is irradiated.

The light receiver 41 also includes an area sensor 42 that generates an electrical signal according to the pattern on the surface of the banknote.
and a condensing lens 43 that condenses reflected light from the banknote Sb onto the area sensor 42.
The area sensor 42 is a two-dimensional sensor in which a large number of line-shaped image sensors are arranged in a direction perpendicular to the line, and is operated by a trigger signal issued from a discrimination control circuit 46 to be described later. Scanning is performed, and the amount of reflected light at a specific position (line or coordinate) in area E is exchanged into an electrical signal, and a waveform signal corresponding to the pattern on the banknote surface is output. In other words, the area sensor 42 has its horizontal direction corresponding to the X coordinate of area E, and its vertical direction corresponding to the Y coordinate of area E.
Depending on the correspondence with the XY coordinates, for example, the surface pattern (line data) in area E is Y=1,
You can read by specifying the line as Y=3,
Furthermore, the read area data is stored in the ROM64.
(described later), it is possible to determine the denomination and front and back of the banknote Sb (details will be described later).

Next, according to FIG. 4A and FIG. 4B, a counting control circuit 45 (turning prevention function, separation stop function, confirmation input function, continuous counting function, amount calculation function) that operates the counting mechanism and discrimination mechanism, respectively; The discrimination control circuit 46 (denomination discrimination function) will be explained.

That is, the counting control circuit 45 has a ROM 47 that stores a counting control program (see FIG. 5A, FIG. 5B, and FIG. 6), which will be described later, and the like.
RAM 4 writes and reads various data according to the program stored in ROM 47
8 and a CPU 49 that controls them. Furthermore, the CPU 49 has an input side I/O
A start switch 52 for instructing the start of counting operation, a detection mode switch 53 for determining the denomination and double feed, and a front/back mode switch 54 for determining front/back are connected through the port 50 and receiver 51. , holder position detection sensors 24A and 24B that detect whether the holder 1 is in the closed position or the open position, a rotary cylinder position sensor 18, a pressure sensor 11, and other operation switches 55 such as a clear switch are connected, respectively. .

In addition to the clear switch, the operation switch 55 includes a mode selection switch for appropriately selecting modes such as count addition, designation (batch), review (check), stamping, and amount calculation, as will be described later. When counting is interrupted when the count ends abnormally, there are 10,000, 5,000, and 1,000 tickets buttons for inputting denomination confirmation for banknotes with an abnormality, and a confirmation button for confirming the denomination confirmation input. There are also confirmation switches (both switches are not shown) such as (also used to confirm the denomination).

The modes selected by the mode selection switch, such as count addition, designation (batch), re-examination (check), stamping, and amount calculation, are based on the above-mentioned denomination and double feed discrimination. The detection mode switch 53 and the front/back mode switch 54 for performing front/back discrimination are in a relationship as shown in the table of FIG. 4B.

In other words, if you select counting addition mode, specification mode, or review mode among the mode selection switches, you need to specify whether to turn the detection mode switch 53 ON or OFF each time you select these modes. (However, when the count addition mode is selected, the detection mode switch 53 is automatically
Also, when the stamping mode is selected from the mode selection switch, the detection mode switch 53 is automatically set to ON, and the detection mode switch 53 is automatically set to ON by the operator.
The work of specifying is now omitted.

Furthermore, when the stamping mode is selected, the detection mode switch 53 is turned on as described above.
is automatically specified as ON, while only once
It is now possible to specify OFF. In other words,
Select the stamping mode and turn the detection mode switch 53
When OFF is specified, (1) when the banknotes are counted once, (2) the detection mode switch is turned OFF.
If you do not press the start switch 52 within 10 seconds after specifying, (3) turn on the detection mode switch 53.
When specified, the detection mode switch 53
is automatically released from the OFF mode to the original ON mode.

Furthermore, when the amount calculation mode is selected, the detection mode switch 53 is automatically designated ON, and it is possible to designate this detection mode switch 53 OFF.

On the other hand, the above-mentioned count addition mode, specification mode,
In the review mode and stamping mode, the front/back mode switch 54 can be turned on or off only while the detection mode switch is set to ON, but in the amount calculation mode, the front/back mode switch 54 is automatically turned on. is designated as OFF, and it is impossible to designate this front/back mode switch 54 as ON.

Of the various modes selected by the mode selection switch, "counting and addition" is also explained in the flowcharts of FIGS. This is a mode in which numerical values are accumulated and added each time a banknote is counted (described later in step 144 in Figure 6). This is a mode in which the separator 25 is operated to separate counted banknotes and uncounted banknotes when the banknotes are bundled (described later in step 110 in FIG. 6). This is a mode to check whether there is a predetermined number of banknotes (steps in Figure 6).
140 (described later in step 140), and furthermore, "sealing" is a mode in which a banknote is re-examined and, if the re-examination result is correct, a seal is placed on the wrapping (described later in step 142 in Figure 6). "Calculation" is a mode in which the total amount of all banknotes loaded in the holder is calculated and displayed (described later in step 146 of FIG. 6).

On the other hand, the start switch 52 shown in FIG.
In this embodiment, the pushbutton 60 (see FIG. 1) provided on the holder 1 constitutes a pushbutton 60, but for example, a sensor (not shown) that detects that a banknote S is loaded in the holder 1 can be activated. switch 52
May be used as

Further, the CPU 49 is connected to a solenoid (printing solenoid) 35, a lamp consisting of a double feed detection lamp 37 or a projector 40, a holder motor 23, and a counting motor 19 via an output side I/O port 61 and a driver 62. , pump motor 21, solenoid valve 16, batch solenoid 28, and bill counter operation panel (not shown)
A display section 63 is connected to the display section 63 for displaying the number of banknotes, presence or absence of an abnormality, etc.

On the other hand, the discrimination control circuit 46 has a ROM 64 that stores discrimination control programs (see FIGS. 7 and 8), and writes and reads various data according to the programs stored in the ROM 64. RAM65 to perform and control these
It is composed of a CPU 66. Furthermore, the above
An area sensor 34 is connected to the CPU 66 via an output I/O port 70 and a drive circuit 71, and the output of this area sensor 34 is connected to an amplifier 72,
A/D converter 73, input side I/O port 74
It is designed to be input to the CPU 66 via.

Note that from the drive circuit 71 to the area sensor 34
The drive signal supplied to the banknote is composed of an X-axis drive signal and a Y-axis drive signal, and by outputting these X-axis drive signals and Y-axis drive signals, the surface pattern at a specific position in area E of the banknote is determined. (area data)
is now read out. When extracting surface pattern data in area E, first output a Y-axis drive signal to determine the Y coordinate of area E (see Figure 2).
The X coordinate of area E may be determined by outputting an X-axis driving signal. For example, set Y to 1 and read the data in area E as line data (X, 1), set Y to 3 and read the data in area E as line data (X, 3), and read these data. Multiple line data (X, 1) (X, 3) etc.
The data may be compared with reference data stored in the RAM 65 (the X-axis and Y-axis of the drive signal correspond to the X-axis and Y-axis of area E shown in FIG. 2, respectively).

On the other hand, similar to the area sensor 34, double feed detection sensors 37 and 38 are connected to the A/D converter 73 via an amplifier 78. Further, an analog switch 7 operated by a switching signal from the output side I/O port 70 is connected between the amplifiers 72 and 78 and the A/D converter 73.
These analog switches 79 and 80 allow the output signal of either the area sensor 34 or the double feed detection sensors 37 and 38 to be sent to the A/D converter 73. It's summery.

Further, the CPU 49 of the counting control circuit 45 and the CPU 66 of the discrimination control circuit 46 are connected to each other via data transfer I/O ports 81 and 82, and can mutually convert data and operate in conjunction. It is configured as follows.

Hereinafter, the contents of the program stored in the ROM 47 of the counting control circuit 45 will be explained along with the operation of the banknote counting machine according to FIGS. 5A, 5B, 9, and 11 to 13. do.

Note that SN in FIGS. 5A and 5B indicates step N in the following explanation, and Tn in FIGS. 9 and 13 indicates timing Tn in the following explanation.

(a) Counting control operation 1 (see Figures 5A, 5B, and 9) <Step 1> Power on <Step 2> The holder 1 is placed in the open position by the output signals of the holder position detection sensors 24A and 24B. If the answer is NO, drive the holder motor 23 to set the holder 1 to the open position (step 3).
If YES, proceed to the next step 4.

<Step 4> Based on the presence or absence of an output from the rotary cylinder position sensor 18, it is determined whether the suction shaft 5 is in the standby position (that is, the position where the suction shaft 5 directly faces the banknotes),
If NO, the counting motor 19 is driven at low speed and the suction shaft 5 is set to the standby position (step 5).
If YES, proceed to the next step 6.

<Step 6> Determine whether or not the mode setting switch has been set. If YES, various mode setting operations, such as specified mode (batch mode),
By operating the review mode (check mode) or the stamping mode, the mode in which these operations were performed is memorized (step 50), and if NO, it is assumed that the mode setting operation has not been performed. (The mode is now in counting and addition mode), proceed to the next step 7.

<Step 7> Start signal (ST) from start switch 52
It is determined whether or not the output has been output, and if NO, the process returns to step 6, and if YES, the process proceeds to the next step 8 (timing T ₁ ).

<Step 8> Based on the outputs of the holder position sensors 24A and 24B, it is determined whether the holder 1 is in the closed position or not. If NO, a holder motor drive signal (HMD) is output and the holder motor 23 is is driven to set the holder 1 to the closed position (step 9), and if YES, proceed to the next step 10 (timing T ₂ ).

<Step 10> A pump drive signal (PMP) is output to drive the pump motor 21, and a solenoid valve drive signal (SV) is output to switch the solenoid valve 16 to the exhaust nozzle 14 side.

<Step 11> Determine whether the suction shaft 5 is at the starting position,
If NO, count motor drive signal (CMD)
is output, the counting motor 19 is driven in the reverse direction at low speed to set the suction shaft 5 to the starting position (step
12), and in the case of YES, proceed to the next step (timing T ₃ ).

<Step 13> Wait for the pressure judgment signal (VSW) to be output, that is, wait for the vacuum pressure in the suction pipe 7 to rise to a predetermined value, and then proceed to the next step 14 (timing T _Four ).

<Step 14> When the pressure discrimination signal (VSW) is output (Step 13), the counting motor drive signal (CMD) is output.
is output, and the rotating barrel 3 and suction shaft 5 start rotating.

<Step 15> The suction shaft 5 counts the bills while turning them over one by one, and every time the rotary cylinder position sensor 18 generates a signal (SNS), a trigger signal (TRG) is generated to retrieve the detection data of the area sensor 42. ) is output. Also, at this time, a counting signal (CNT) is output to count (or discriminate) the banknotes (timings _T6 to Tm).

<Step 16> Determine whether or not the pressure judgment signal (VSW) is output, that is, whether the vacuum pressure in the suction pipe line 7 is in a state where it cannot be increased (OFF),
When the separator 25 is turned OFF (timing Tm ₊₁ ), or during the batch mode as described later, the separator 25 operates and the suction shaft 5 finishes counting the set number of banknotes, thereby preventing subsequent turning over of banknotes. In either of these cases, it is determined whether the counting has ended normally without error detection (abnormality in discrimination, different denominations, discrepancy between front and back sides, detection of double adsorption) as described later, and if YES is selected. If yes, proceed to the next step 17; if NO, proceed to step 30.

Note that, as will be described later, the detection of residual errors and number-of-sheets mismatch errors is determined after normal termination, so these are included in normal termination.

<Step 17> Stop the counting motor 19 and pump motor 21.

In addition, in the case of this normal termination, so that all the bills turned over by the suction shaft 5 are together,
Similar to the conventional device, a brake signal (BRK: see FIG. 14) is applied to the counting motor 19 after a short delay, and the counting motor 19 is stopped.

<Step 18> In the same way as Steps 4 and 5 described above, it is determined whether or not the suction shaft 5 is in the standby position, and if NO, the counting motor 19 is driven at low speed to move the suction shaft 5 to the standby position. (step 19),
If YES, proceed to step 20.

<Step 20> As described later, it is determined whether the holder open signal is output automatically or by operating the clear button (clear switch) depending on the processing mode, and if YES, the step is executed. 2 return (timing Tn), if NO, wait at step 20. When the process returns to step 2 (timing Tn), it is determined whether or not the holder 1 is opened, and the holder motor drive signal (HMD) is output until the holder 1 is opened.

Then, when the holder opens (step 4; timing Tn ₊₁ ), the motor drive signal (HMD) is activated.
At the same time as turning off, a counting motor drive signal (CMD) is output to drive the counting motor 19. When the suction shaft 5 moves to the standby position by driving the counting motor 19, the output of the rotary cylinder position sensor 18 turns ON, and at the same time, the counting motor 19 is stopped (timing Tn _{+ 2} ).

When the suction shaft 5 is stopped at the standby position in this way, it becomes ready to start counting immediately by the next start signal (step 7).
The next preparation is complete.

<Step 30> As explained briefly in step 16 above,
It is determined whether or not the separator 25 is activated by error detection (discrimination abnormality, different denomination, front and back mismatch, double suction detection) to prevent the suction shaft 5 from turning over the banknotes, resulting in an abnormal termination of counting. death,
If YES, proceed to step 31; if NO, return to step 15.

As mentioned above, as long as the pressure judgment signal (VSW) is output (ON),
Alternatively, as long as the batch device (separator 25) is not activated, the steps 15, 16, and 30 are looped and counting operations are performed as described later.

<Step 31> The counting motor 19 is suddenly stopped, and the pump motor 21 is also stopped.

The processing at this time will be explained in detail with reference to the state explanatory diagrams shown in FIGS. 11 and 12 and the time chart shown in FIG. 13.

First, as shown in FIG.
detects and outputs the rotary cylinder position sensor output signal (SNS)
By timing T101, which is the rising edge of
The discrimination process for banknote Sa is completed, and this banknote Sa
Suppose that is determined to be an abnormal banknote.

Then, at this timing T101, the next banknote
The peeling operation by the suction shaft 5 against Sb is
A separator 25 of the batching device prevents this, as shown in FIG.

At the same time, as shown in FIG. 13, a counting motor brake signal (BRK) is applied instead of the counting motor drive signal (CMD), and the rotation of the rotary cylinder 3 on which the suction shaft 5 is arranged is suddenly decelerated. Ru.

Thereafter, at timing T101, the actuating piece 17 detected by the rotary cylinder position sensor 18 continues until it is no longer detected by the rotary cylinder position sensor 18, that is, until the rotary cylinder position sensor output signal (SNS) falls. , within the rotation range (first
Within the rotation range from the position shown in FIG. 1 to the position shown in FIG. 12), the rotation of the rotary cylinder 3 is completely stopped at timing T102 shown in FIG. 13, for example.

At this timing T102, as shown in FIG. 12, the abnormal banknote Sa is also an uncounted banknote (the frontmost banknote is represented by Sb).
Both the counted banknotes Sc and Sd are separated and stopped at a separate position.

<Step 32> In this way, when the abnormality ends, the denomination of the abnormal banknote is visually confirmed by the operator as described later, but as shown in FIG. Since both the banknotes and the counted banknotes are stopped at a separate position, visual confirmation by the operator can be easily and quickly performed.

Then, by operating the confirmation switch, it is determined that the continuous count is YES, and the process proceeds to step 34.

On the other hand, while the confirmation switch is not operated in this step 32 (while the continuation count is NO), it is determined in step 33 whether or not the clear button has been operated, and if the clear button has been operated (YES), the step From step 33, the process returns to step 2 in the same way as step 20 described above, and if step 33 is NO, the process waits in a loop of steps 32 and 33.

<Step 34> If the confirmation switch is operated in step 32 and it is determined that continuous counting is YES, step 30 is executed.
The separator 25 is activated in the event of an abnormality.
The batch state (a state in which the separator 25 prevents the bill turning operation by the suction shaft 5) is released, the process returns to step 10 (returns to timing T2 shown in FIG. 9), and the pump motor 21
As soon as the suction shaft 5 is started to be driven, a process is performed to reverse the suction shaft 5 from the standby position to the start position, and then,
By outputting the pressure judgment signal (VSW),
The operation of flipping the banknotes and determining the denomination from the point of interruption will be automatically resumed.

In addition, in the process of separating and stopping abnormal banknotes by suddenly stopping the counting motor in step 31 described above, as shown in FIG. Visual confirmation may be difficult to perform.

In order to solve this problem, the suction shaft 5 (rotary tube 3) may be reversed from the separation stop state position shown in FIG. 12 to the banknote Sa position shown in FIG. 1.

That is, the process of returning the suction shaft 5 to the standby position is
* Between step 31 and step 32 in Figure 5A
Step 40 shown in the flowchart of Figure 5B at the marked position.
~It would be good to add the processing in step 43.

The processing of steps 40 to 43 will be explained below.

<Step 40> In order to return the suction shaft 5, which was stopped as shown in FIG. 12 in step 31, to the standby position shown in FIG. (see timing T103 in the figure) until the suction shaft 5 returns to the suction shaft starting position shown in FIG. 11 (while this step 40 is NO).
Counting motor 19 is driven in reverse at low speed (step
41), when the suction axis is returned to the starting position (when this step 40 is YES: timing T1 in Fig. 13)
04), proceed to the next step 42.

<Step 42> After the suction shaft 5 is returned to the suction shaft starting position shown in FIG. 11, a counting motor drive signal (CMD) is output in the forward rotation direction (timing T1 in FIG. 13).
05) until the suction shaft 5 is set to the suction shaft standby position shown in FIG.
(during NO), the counting motor 19 is driven forward at low speed (step 43), and when the suction shaft is set to the standby position (when this step 42 is YES: see timing T106 in Fig. 13), Fig. 5A Proceed to step 32 of the flow.

By the way, when the continuation count (step 32) becomes YES, the batch state is canceled (step 34), the drive of the pump motor 31 is restarted, and when the suction shaft 5 is further reversed to the suction shaft start position (step
11, 12), in order to prevent the banknote Sa confirmed at the time of separation stop from being accidentally stacked on the front side (banknote Sb) of uncounted banknotes whose peeling is prevented by the separator 25, step 34 is performed. Just before the
Rotate the suction shaft 5 (rotary cylinder 3) in the normal direction for even one or two pieces to separate the banknotes Sa that have been confirmed to have been separated and stopped, as well as the banknotes Sc that have already been counted.
It is also an effective process to overlap Sd.

Next, the counting processing flow in the CPU 49 will be explained with reference to FIG.
Figures 7 and 8 regarding the determination processing flow in
This will be explained with reference to the figures.

◇Counting control operation 2 (see Figure 6) <Step 100> Start <Step 101> Determine whether the detection mode switch 53 is turned on, that is, whether it is necessary to read the pattern on the banknote surface. , in the case of YES, outputs the discrimination ON signal and the front/back mode signal (however, only when the front/back mode switch 54 is ON, the same applies hereinafter), and lights up the double feed detection lamp 37 and the floodlight 40 (step 102). ), and further supplies these banknote discrimination ON signals and front/back mode signals to the discrimination routine shown in FIG. 7 (indicated by arrows).

If the detection mode switch 53 is OFF, it is determined that only counting is to be performed, and the process proceeds to the next step 103.

<Step 103> After the start operation is performed and the suction shaft 5 is moved from the standby position to the start position, the process waits in step 103 until the pressure judgment signal (VSW) is output.

<Step 104> Detects the rise of the rotary cylinder position sensor output signal (SNS), and if it becomes YES, proceed to the next step.
Proceed to 105.

In addition, this rotary tube position sensor output signal (SNS)
The start of forward rotation of the counting motor 19 is confirmed by the detection of the rise of the count motor 19.

<Step 105> The trigger signal (TRG) is raised at the same timing as in step 104, and the output of this trigger signal (TRG) is supplied to the discrimination routine shown in FIG. 7 (indicated by an arrow).

<Step 106> Rotating tube position sensor output signal (SNS) ON-
The OFF state is detected, and if it is ON (YES), it is determined whether the pressure judgment signal (VSW) is ON (step 107), and this step 107 is
If NO, a discrimination OFF signal is output (step
130), and counting motor 19, pump motor 21
drive and double feed detection lamp 37, floodlight 4
The lighting of 0 is stopped (step 131). Further, in step 107, if the pressure judgment signal (VSW) is output (YES), the next step is performed.
Proceed to 108.

<Step 108> It is determined whether the detection mode switch 53 is turned on or not. If YES, proceed to step 109; if NO, proceed to step 110.

<Step 109> If a different denomination is detected, if a discrepancy between the front and back sides is detected in the front/back discrimination mode, if it is determined that there is a discrimination abnormality because it does not match all the reference patterns, or if double adsorption is detected. In this case, it is determined whether or not there is an input of an error signal (indicated by an arrow) output from the determination processing flow, and if YES, the batch solenoid 28 is turned on and the separator 25 is operated to cause the suction shaft 5 to The turning operation is interrupted (step 112), and if the operation is NO, the process proceeds to step 110.

<Step 110> Determine whether the batch mode is ON or not. If NO, return to step 106; if YES, proceed to step 111.

<Step 111> The number of banknotes is determined, and if it is determined that the banknote count is less than the predetermined number (NO), the process returns to step 106, and if the banknote count has reached the predetermined number. If it is determined (YES), the batch solenoid 28 is turned on to separate the counted paper from the uncounted banknotes (step 112), and then a discrimination OFF signal is output (step 113) (this discrimination is OFF). The signal is supplied to the discrimination processing flow as shown by the arrow), and the driving of the counting motor 19 and pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 are stopped (step 114). Then, proceed to the next step 115.

<Step 115> The batch solenoid 28 is turned on, the separator 25 is operated, and the peeling operation by the suction shaft 5 is interrupted due to error detection (discrimination error, different metal type) as explained in step 30 above. , front and back mismatch, or double adsorption detection). If the counting is interrupted due to the abnormal termination, the process proceeds to step 160; otherwise, the process proceeds to step 116.

<Step 116> Separator 2 operated during the above batch processing
5 has been performed, or whether a clearing operation has been performed to release the residual error set in step 135 or the count mismatch error set in step 148, which will be described later. , if YES, step 117
Proceed to. <Step 117> An open signal (see step 21) is output to holder 1, and this flow ends.

Next, steps 120 to 123 will be explained.

<Step 120> In step 106, the ON-OFF state of the rotary cylinder position sensor output signal (SNS) is detected,
If it is in the ON state, the routine from step 106 to step 110 (or step 111) continues, and when it becomes OFF, this step is executed.
Move to 120. Then, as in step 107, it is determined whether the pressure judgment signal (VSW) is ON or not, and if this determination is NO, the process proceeds to the next step 130, as in step 107,
A discrimination OFF signal is output (step 130), and the driving of the counting motor 19 and pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 are stopped (step 131). Further, if the output of the pressure determination signal (VSW) is YES, the process proceeds to step 121.

<Step 121> It is determined again whether the rotary tube position sensor output signal (SNS) has risen. If NO, return to step 120. If YES, output the trigger signal (TRG) and Step 122) (This
TRG is supplied to the discrimination processing flow as shown by the arrow), and after counting the counter CNT by 1 (step 123), the process returns to step 106.

Next, steps 130 to 148 will be explained.

<Step 130> As mentioned above, if the output of the pressure judgment signal (VSW) is not detected in steps 107 and 120,
For example, if the banknotes at the counting position are not picked up or there are no banknotes to be counted, the
An OFF signal is output (this discrimination OFF signal is supplied to the discrimination processing flow as shown by the arrow),
Then, after stopping the driving of the counting motor 19 and the pump motor 21, and stopping the lighting of the double feed detection lamp 37 and the floodlight 40 (step 131), the process proceeds to step 132.
Proceed to.

<Step 132> Determine whether or not the detection mode switch 53 is turned on. If NO, proceed to step 140; if YES, proceed to step 133.

<Step 133> If the discrimination routine does not output an end signal (indicated by an arrow) for a certain period of time (step 134), for example, even though the banknotes to be counted have been set, If suction has not been carried out, a flag indicating a residual error is set in a predetermined area of the storage section (RAM 48 or CPU 49) (step 135), and then the process proceeds to the next step 116.

Further, if an end signal is output from the determination processing flow shown in FIG. 7, the process advances to the next step 140.

<Step 140> It is determined whether the mode setting is set to the number of sheets check mode. If NO, proceed to step 144; if YES, proceed to step 141.

<Step 141> It is determined whether the counted value of the banknotes matches the number set in the number of banknotes check mode, and if NO, a flag indicating a mismatch error is placed in a predetermined area of the storage unit. Step
148), proceed to step 116. Further, if the set number of sheets and the counted value match (YES), the process advances to the next step 142.

<Step 142> Determine whether or not the mode setting is set to stamping mode, and if YES, stamping solenoid 3
5, stamp the obi seal (step 143),
Moreover, in the case of NO, the process proceeds to the next step 144.

<Step 144> Determine whether or not the mode setting is set to addition mode. If YES, add the counting results of the previously counted banknotes and store the addition result in the storage unit (Step 144). 145), and if NO, proceed to step 146.

<Step 146> It is determined whether the mode setting is set to the amount calculation mode, and if YES, the total amount of the counted banknotes is displayed (step 147), and
If NO, the process advances to step 117 and the counting process ends.

In addition, in the amount counting mode, the step
147, but instead of incrementing the counter CNT by 1 in step 123, the total amount is calculated and displayed based on the denomination code output in step 216, which will be described later. It is also possible to do so.

Next, steps 160 to 181 will be explained.

<Step 160> As mentioned above, in step 115, the batch solenoid 28 is turned ON to operate the separator 25, and the cause of interrupting the peeling operation by the suction shaft 5 is error detection (discrimination error, different metal type). ,
In the case of abnormal termination due to detection of discrepancy between front and back sides or detection of double adsorption, it is determined whether the mode is monetary counting mode or not, and if YES, the process proceeds to the next step 161.
If NO, proceed to step 180.

<Step 161> An abnormal state in which the banknotes are separated and stopped at the position shown in Figure 12 or Figure 1 (a position away from both the uncounted banknotes Sb and the counted banknotes Sc and Sd) while the banknotes are suspended in the batch state. Visually check the denomination of the banknote Sa, press the denomination button corresponding to the denomination of this abnormal banknote,
In this step 161, it is determined whether the 10,000 ticket button has been operated, and if YES, a code representing a 10,000 ticket is set (a flag is set: step 162), similar to step 216 in the determination processing flow described later.
If NO, proceed to the next step 163.

<Step 163> In the same way as step 161, it is determined whether the 5,000-note button has been operated, and if the answer is YES, a code representing the 5,000-note button is set (step 164), and if the answer is NO, the next step is executed. Proceed to 165.

<Step 165> As in steps 161 and 163, it is determined whether the 1,000-ken button has been operated, and if YES, a code representing 1,000 tickets is set (step 166), and if NO, proceed to the next step. Proceed to 167.

<Step 167> Determine whether or not the denomination code for the abnormal banknote has been set in any of steps 161, 163, and 165 above, and if YES, proceed to the next step.
Proceed to step 168; if NO, proceed to step 169.

<Step 168> After setting the denomination code for the abnormal banknote, it is determined whether the confirmation button to confirm this has been operated,
If YES, proceed to step 170; if NO, proceed to the next step 169.

<Step 169> If the visually confirmed abnormal banknote Sa is a double-adsorbed banknote, or if it is a sheet of paper such as a receipt that has been sandwiched between banknotes, this A clear operation is required to remove the
As in step 116, it is determined whether the clear button has been operated or not. If YES, proceed to step 117 and finish counting; if NO, return to step 161 and enter the denomination code for the abnormal banknote. Do it like this.

<Step 170> When the denomination code for the abnormal banknote is set and the confirmation operation is performed, the set denomination code is output in the same way as in step 216 in the discrimination processing flow described later, and in the next step 171, the next denomination code is output. It is cleared for denomination input and proceeds to the next step 172.

<Step 172> If the denomination and code for the abnormal banknote are input in steps 161 to 170,
Alternatively, if the denomination of the abnormal banknote in the different denomination detection mode is confirmed in step 180, which will be described later, that is, if the continuous counting is determined to be YES in step 22, then in step 112, the abnormal banknote is confirmed. Turn off the batch solenoid 28 that was turned on at the end and turn off the separator 25.
The batch state (a state in which the separator 25 prevents the bill turning operation by the suction shaft 5) is canceled, and the process returns to step 101.

Then, the discrimination ON signal and the front/back mode signal (however, only when the front/back mode switch 54 is ON) are outputted, and the double feed detection lamp 37 and the floodlight 40 are turned on (step 102).
Thereafter, the pressure determination signal (VSW) is output, and the banknote flipping and denomination determination operation from the point of interruption is automatically restarted.

<Step 180> If the counting interruption due to abnormal termination in step 115 described above occurs in a mode other than the amount calculation mode, that is, a banknote of a different denomination from the banknotes that have already been turned over and counted is detected. In the case of the normal different denomination detection mode, which is interrupted when an abnormal banknote is detected, it is checked whether the abnormal banknote is of the same denomination as the banknote that has already been turned over and counted. If YES, proceed to step 172 to enable continuous counting; if NO, proceed to the next step 181.

<Step 181> As in steps 116 and 169, it is determined whether the clear button has been operated or not. If YES, proceed to step 117 to finish counting; if NO, return to step 180. These two steps 180,
181 loop, and an instruction can be input as to whether or not the abnormal banknote is of a different denomination.

In addition, in the flow shown in FIG. 6, it is configured so that only confirmation input can be performed for one bill, and as a result, in the case of double adsorption detection, only the clear operation can be processed. In the case of the invention, the double suction banknotes are separated and stopped at the position shown in FIG. 12 or 1 (a position away from both the uncounted banknotes Sb and the counted banknotes Sc and Sd), You can check the number (and denomination composition) of adsorbed banknotes.
Therefore, it is also possible to configure the system so that the number of sheets data (and the denomination code for the number of sheets) can be input at the time of confirmation.

In this case, since the double adsorption banknote Sa itself has already been counted as one by the counter CNT, the input number of banknotes data is subtracted by 1 and the data is added to the counter CNT.

Further, since all denomination codes are valid, they are used as they are for calculating the amount.

Next, the determination processing flow in the CPU 66 will be explained with reference to the time charts of FIGS. 7, 8, and 10.

<Step 200> Start <Step 201> Determine whether the trigger signal (TRG) (indicated by the arrow) is output from the counting routine and select YES.
In this case, proceed to the next step 202.

<Step 202> It is determined whether or not the determination ON signal (indicated by the arrow) has been output from the counting routine. If NO, the process returns to step 201. If YES, the analog switch 80 shown in FIG. 4 is activated. Select the output of the double feed detection sensors 37 and 38 to the amplifier 78,
Capture via A/D converter 73, RAM
65 (step 203), step 204
Proceed to.

<Step 204> Based on the error codes set in step 215, step 223, and step 232, it is determined whether there is a mixture of different denominations, there is a discrepancy between the front and back sides, and there is a discrimination error (mixture of abnormal banknotes). Detection of mixed denominations, discrepancies between front and back sides, and discrimination abnormalities will be described in steps 214, 222, and 231).If YES, an error signal and error code are output.
After displaying the error details on the display section 63 (step 205), the process returns to step 201. The error signal output at step 205 is supplied to step 109 of the counting routine in FIG. 6 as indicated by the arrow.

Further, if there is no mixing of different denominations, no discrepancy between the front and back sides, and no discrimination abnormality (NO), the process proceeds to the next step 206.

Note that when the first trigger signal (TRG) is output, steps 215, 222, and 232 have not been passed and no determination has been made, so the first step 204 is always NO and the process proceeds to step 206.

<Step 206> In step 203, double feed detection sensors 37 and 38
Based on the detection data taken in from the banknote and the double comparison level, which is the discrimination standard set in step 218 (described later), it is determined whether or not the banknote has been double attracted, and if YES, an error signal is sent. and an error code, and the error details are displayed on the display section 6.
3 (step 207), the process returns to step 201.

The error signal output in step 207 is supplied to step 109 of the counting routine in FIG. 6 as indicated by the arrow.

If NO, that is, if it is determined that there is no double adsorption, the process proceeds to the next step 208.

Note that, as in step 204, when the first trigger signal (TRG) is output, the banknote Sa for which double adsorption should be determined does not exist in the position shown in Figure 1, and the reference double comparison level has not been set. Therefore, this step 206 is always NO and the process proceeds to step 208.

<Step 208> Select the analog switch 79 shown in FIG.
By storing the output of the area sensor 34 in the RAM 65 via the amplifier 72 and the A/D converter 73, area data in the area E (data on the N line) is captured. Note that this area data is taken in based on the flow shown in FIG.

That is, when a capture signal is output (step 300), after setting Y to 0 and X to 0 (step 301), the process proceeds to the next step 302. and,
In this step 302, it is determined whether or not the output of the necessary N lines of data (line data) has been completed.If YES, a determination start signal is output (step 303), and the main Return to routine. Also, if the answer is NO in step 302, the data of the specified N line is transferred to step 312.
Steps 304 to 311 are looped until the data is output, and when the data is output, the process proceeds to step 303 as described above.

When the line-by-line acquisition of area data is completed in this manner, the process proceeds to the next step 209 shown in FIG.

<Step 209> Check whether the data imported in step 208 has no pattern (i.e.,
Whether it is a black pattern on the surface 1b of the first half holder 1)
If it is YES (no data), after outputting the end signal (step 210), step
Return to 201. The end signal output at step 210 is supplied to step 133 of the counting routine in FIG. 6 as indicated by the arrow.

Further, if the captured area data is of a level having a pattern (NO), the process advances to the next step 211.

<Step 211> It is determined whether the setting mode is set to the amount calculation mode, and if YES, the banknotes loaded in the holder are individually determined to determine which denomination of the banknotes they are. , proceed to step 213, and if NO, proceed to the next step 212.

<Step 212> It is determined whether or not the banknote sucked by the suction shaft 5 is the first one. If YES, proceed to step 213; if NO, proceed to step 230.
Proceed to.

<Step 213> For the area data of the first banknote imported in step 208, a total of 12 patterns (4 x L patterns) of the current 3 denominations (L denominations) stored in the ROM 64 are applied. The data data (for one denomination, there are four patterns of front, back, forward and reverse) is compared, and the process proceeds to the next step 214.

<Step 214> As a result of comparing the area data of the first banknote with the reference data of the 12 patterns, it is determined whether there is a matching pattern, and if NO, it is determined that the banknote is an abnormal banknote that cannot be identified. As the storage unit (RAM
A flag indicating a discrimination abnormality is set in a predetermined area of step 65) (step 215), and the process returns to step 201.

If there is a matching pattern (YES), a flag indicating that the identified banknote is one of the three denominations is set in a predetermined area of the storage unit (RAM 65) (step 216). ), and after setting a flag indicating the front and back sides of the banknote (step
217), based on the determined denomination and front and back information.
The storage unit (RAM65) stores the double comparison level, which is the discrimination standard for double adsorption, stored in the ROM64.
After setting (step 218), proceed to step 219.

As described above, in the amount calculation mode, the counting control circuit 45 automatically calculates the total amount of the flipped bills at any time based on the denomination code output in step 216, and also performs this calculation. The results can also be displayed at any time on the display section 63 as described above.

<Step 230> On the other hand, if it is determined in the above-mentioned step 212 that the bill attracted by the suction shaft 5 is not the first bill, the area data of the bill taken in in step 208 and the area data of the bill are stored in the ROM 64. specified denomination (denomination set in step 216)
The process proceeds to the next step 231 after comparing only the reference data of four patterns of front and back, forward and reverse.

<Step 231> As a result of comparing the area data of the banknote with the reference data of the four patterns, it is determined whether there is a matching pattern, and if NO, this banknote is a banknote of a different denomination (strictly speaking, (There may also be banknotes with abnormal identification)
, a flag indicating a different denomination is set in a predetermined area of the storage section (step 232), and the step
Return to 201.

Also, if there is a matched pattern (YES)
As described above, a flag indicating the front and back sides of the banknote is placed in a predetermined area of the storage unit (step 217).
Furthermore, in step 218, the amount of transmitted light of the banknote is set in a predetermined area of the storage section, and the process proceeds to the next step 219.

<Step 219> It is determined whether the front/back mode switch 54 is turned on. If NO, proceed to step 201; if YES, proceed to the next step 220.

<Step 220> Determine whether or not this bill is the first one, and select NO.
If YES, proceed to step 222; if YES, proceed to the next step 221.

<Step 221> The front and back codes of the first banknote set in step 217 are stored in the storage unit as front and back reference data.
It is set in the RAM 65, and based on this front/back reference data, the front/back side of the banknote is determined (step
222).

<Step 222> The front and back codes set in step 217 are compared with the front and back reference data set in step 221 to determine whether the second and subsequent banknotes match the front and back of the first banknote. If they match (YES), return to step 201; if they do not match (NO), proceed to the next step 233. In step 223, a predetermined area of the storage section is recorded to indicate that the front and back sides do not match. After setting the flag indicating
Go back to step 201 and repeat the steps above.
Repeat steps 201 to 232.

Note that the timing of the above-mentioned trigger signal (TRG), duplex data capture, etc. is described in the timing chart of FIG. If these trigger signals (TRG), the timing of importing double data, etc. correspond to the step numbers in FIG. 7, the discrimination trigger signal corresponds to step 201,
The double data acquisition timing corresponds to step 203, below, the error check timing corresponds to step 204, and the double check timing corresponds to step 203.
206, the area data import timing corresponds to step 208, the end check timing corresponds to step 209, and the discrimination processing timing corresponds to steps 211 to 214 and steps 230 and 231. The multiple comparison level and error set timing correspond to steps 216 to 218 and steps 215, 223, and 232, respectively.

In addition, in this determination processing flow, when determining the denomination of the second and subsequent coins in a mode other than the amount calculation mode, that is, when both steps 211 and 212 are NO, the error code is set so that only the different denomination code can be output. Immediately before step 232 of this discrimination processing flow, a comparison is made with the remaining eight patterns to determine whether there is a matching pattern, and if there is a matching pattern, the pattern is left as is. Proceed to step 232 to set the different denomination code, and if there is no matching pattern, proceed to step 232.
It is also possible to proceed to 215 and set a discrimination error code.

The bill counting machine configured as described above reads the front and back patterns of the bill, determines its denomination, and outputs a denomination code (step 216), while outputting an error code when an error is detected. When the denomination cannot be distinguished, a discrimination error code is output (steps 215, 205), when a different denomination is detected, a different denomination code is output (steps 232, 205), and when a discrepancy between the front and back sides is detected, a discrepancy code is output (steps 223, 205).
205), when double suction is detected, an error code is output (steps 218, 207), the bill turning operation is interrupted by the suction shaft 5 (steps 109, steps 112 to 114), and the suction shaft 5 is disposed. suddenly stop the rotary cylinder 3 (steps 30 to 31),
The abnormal banknote Sa is stopped by a suction shaft 5 at a position away from both uncounted banknotes and counted banknotes, and when this separation stop is interrupted, the abnormal banknote is visually confirmed.

When this abnormal banknote is confirmed (steps 168 and 180), the suspended state in which flipping was prevented in the separation and stop state is canceled (step 168 and 180).
172), automatically resumes the bill flipping and discrimination operation from the point in time when this separation stop was interrupted (step 101).
~) I did it.

Therefore, according to this banknote counting machine, even if an error signal is output and the banknote discrimination process is interrupted, abnormal banknotes are separated from uncounted banknotes and counted banknotes by the suction shaft during this interruption. Since the banknotes can be stopped in a separated state at the same position, abnormal banknotes can be easily checked, and after this check, the banknote flipping and discrimination operation from the point at which the separation and stop was interrupted can be automatically resumed. This eliminates the hassle of manually flipping over and checking the last abnormal banknote that was turned over, and the need to restart denomination discrimination from the beginning, unlike conventional counting machines. This eliminates the need for complicated operations, making it possible to efficiently count and distinguish banknotes.

Furthermore, when confirming the abnormal banknote, the denomination thereof can be input (steps 161 to 166);
When this input is made (steps 167, 168), the interrupted state in which flipping is prevented in the separation stop state is canceled (step 172), and the flipping judgment of the banknote from the time when the separation stop is interrupted is performed in the same manner as described above. In addition to automatically restarting the operation, the denomination code (output in step 170) that was set after checking the denomination at the time of interruption, and the denomination code set at the time of interruption, and at the time of counting before and after the interruption, are
It is also possible to calculate and display the total amount of banknotes loaded in the holder based on the automatically determined and set denomination code (output at step 216) (steps 145, 147).

Therefore, according to the banknote counting machine configured in this manner, even if an error signal is output and the banknote discrimination process is interrupted, abnormal banknotes are counted by the suction shaft as well as uncounted banknotes at the time of interruption. Since the banknotes are stopped in a separate position away from used banknotes, it is possible to easily confirm the denomination of abnormal banknotes, and input the denomination information. After confirmation, it is possible to automatically restart the banknote flipping judgment operation from the point at which the separation stop was interrupted, so unlike conventional counters, it is possible to manually pick up the last abnormal banknote that was turned over. This eliminates the hassle of turning the paper over and checking it, and the complicated operations of starting over to distinguish the denomination from the beginning, making it possible to count and distinguish bills more efficiently. It is possible to accurately calculate the total amount of banknotes.

In addition, when changing the program for discriminating Japanese banknotes to a program for discriminating US dollar banknotes, this is done by replacing the ROM 64 or the like.

Further, in the discrimination control circuit 46 described above, the line data is extracted along the X axis, but the line data is not limited to this, and may be extracted along the Y axis.

Furthermore, as a sensor for reading the surface pattern in the area E, in place of the area sensor 34, a plurality of one-dimensional image sensors are arranged at intervals with respect to the Y-axis or the X-axis shown in FIG. The detected data may be read out by specifying a column.

``Effects of the Invention'' As explained in detail above, the surface pattern of a banknote is read, the denomination is determined, and a denomination code is output, while an error code is output when an abnormal banknote is detected. At the same time, the turning operation of the banknotes is interrupted, and at the same time, the rotary tube in which the suction shaft is arranged is suddenly stopped, and the abnormal banknote is stopped by the suction shaft at a position away from both the uncounted banknotes and the counted banknotes, and the banknotes are separated. The system is configured to check the abnormal banknote when the stop is interrupted, and when this abnormal banknote is confirmed, the interrupted state in which flipping has been prevented is canceled, and the banknote is turned over from the point of interruption to determine the denomination. According to the first aspect of the invention, in which the operation is automatically restarted, abnormal banknotes can be easily confirmed at the time of interruption, and the operation of turning over the banknotes and determining the denomination from the time when the separation stop is interrupted is automatically performed. This has the effect of making it possible to restart the project.

Furthermore, based on the first invention that allows easy confirmation of abnormal banknotes that are stopped at a position away from both uncounted banknotes and counted banknotes by the suction shaft, it is also possible to input the denomination of the abnormal banknote. According to the second invention, the total amount of banknotes loaded in the holder is calculated based on the denomination information output during the flipping operation of the suction shaft and the denomination information inputted at the time of interruption. This has the effect of making it possible to calculate accurately.
